IMPROVEMENT IN PORCELAIN BLOCKS FOR DENTAL .FILLINGS.
Specification forming part of Letters Patent No. 139,012, dated May 20, 1873; application filed January 29; 1873.
To all whom it may concern:
Be it known that I, CHARLES H. MACK, of the city, county, and State of New York, have invented Porcelain Blocks for Dental Fillings in Natural Teeth; and I- do hereby declare the following to be a full and exact description thereof, referencebeing had to the accompanyin g drawing making apart of this specification, in whicha represents the labial surface of a tooth in which a cavity is to be filled. 1) represents the side and othe end of a porcelain block designed for a dental filling. d and 0 represent varied elongated forms of these blocks. f and g are side views of the same with bent platinuml pins for fastenings. h is side view of block with end undercut for fastening.
The object of this invention is to furnish a durable material for dental fillings which shall closely resemble the natural tooth structure, and also to aid the dentist in his manipulations by having the porcelain blocks, as de scribed, formed in desirable and various patterns for his convenient use. The mode of applying and attaching these porcelain blocks is to first select a block the shape of which corresponds nearly with the shape of the cavity to be filled. This block is to be closely fitted to the cavity, when it will be ready for insertion and attachment. The block is secured within the cavity by means of any of thevarious preparations of oxychloride of zinc, Cement Plombe, Guillois Cement,
Os Artificial, or other plastic material used for filling the natural teeth. A little of either of these preparations, while at a proper plastic or semi-fluid consistency, should be placed in the bottom and against the walls of the cavity. The porcelain block should be immediately forced into the cavity and into the plastic cement previously placed there. In this way the cement is forced well into the under-cuts and uneven surfaces of the porcelain block, and also about the bent or headed plati num pins and when the cement becomes granulated (for which a very brief space of time is required) a most reliable and permanent fastenin g is secured. After this the porcelain block may be ground, finished, and polished even with the tooths surface, and the operation is complete.
For dental fillings in labial surfaces which are frequently exposed to view, this mode of operating is especially desirable. By this we avoid the unsightly glare of gold fillings often seen in the natural teeth.
Claim.
